A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Evidence of austenite memory in PH 15-5 and assessment of its formation mechanism

Materials & Design, 2019
Austenite memory and subsequent spontaneous recrystallization during austenitization is stated for some types of soft martensitic stainless steels such as X4CrNiMo16-5-1 or 13Cr5Ni but have not been proposed for the commercial alloy PH15-5 until now ...

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Heterostructure enables new deformation mechanisms to enhance strength and work hardening

Materials Research Letters
Reflection of geometrically necessary dislocations (GNDs) has been reported effective in increasing strength and ductility of dual-phase alloys. However, this mechanism is rarely observed in conventional single-phase alloys. Here we report the activation

A 3D-Printed SFE-Graded Alloy Mitigates Cryogenic Discontinuous Plastic Flow and Hydrogen Embrittlement. [PDF]

Adv Sci (Weinh)
A novel strategy features gradient composition and stacking fault energy‐tuned (CoCrMn)100‐2xFexNix fabricated via in situ alloying additive manufacturing. This design circumvents cryogenic discontinuous plastic flow and hydrogen embrittlement of metallic materials under quasi‐static loading and hydrogen‐rich environment relevant to lunar polar ...

Nano‐Architected Metallic Metamaterial With Enhanced Fatigue Resistance via Dislocation Starvation

Advanced Materials, EarlyView.
Nanoscale Ni single crystals exhibit remarkable fatigue resistance over an order of magnitude higher than that of bulk single crystals through dislocation starvation. By translating this mechanism into geometric nano‐architecture, nano‐architected Ni single‐crystal metamaterials achieve about twice the fatigue resistance of the bulk, despite their ...

Defect‐Engineered Microwave‐Responsive Ni@C Composites From Waste PET for Catalytic Plastic Upcycling

Advanced Materials, EarlyView.
A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain

Quantitative Process-microstructure-property Interplay in Ti60 Alloy: A Mechanistic Model for Residual Stress and Grain Refinement Gradients Induced by Impact Post-treatment

Engineered Science
This study systematically compares the effects of laser shock peening without coating (LSPwC) and shot peening (SP) on the microstructure and mechanical properties of near-α Ti60 alloy, addressing the knowledge gap in strain-rate-dependent deformation ...
